Hi, did you try downloading the screen from the Fly-Back?

Hi. Comment the voltage at the output of the chhy corresponding fhyback. 180v
Lower the scrin further to 0 v the image has to darken. Nothing should be seen. .
Check the ABL circuit for all components, welds, and printed. Measure and comment on the tension. In what way do you say you go crazy by regulating brightness and contrast?

GOOD DAY COLEGAS! I MISSED THE VIDEO AND AUDIO OUTPUT CONNECTOR THAT IS ON THE SIDE APARTMENT IN ANOTHER CONNECTOR THAT IS NEAR THE EEPROM MEMORY AND LIGHTED THE TV AND THIS IS NEAR THE OUTPUTS OF THE TUNER WOULD THAT WHY I PRESENT THE FAILURE?

That mistake is very common, but it doesn't break anything, I tell you from my own experience. regards

A video voltage of 295v is not logical. did you measure well? - the tension + b, the width and height are normal?

I do not want anyone to be excluded from my assessment. What happens is that the forum is not widely used.

Solution to this case: there is a 250v 22mf capacitor. In that same line we follow the tension and there is a jumper that goes to the connection xs433, which was broken or mediates a resistance, I did not locate it and it is near there at the top is the connection of a cable of the yoke that It goes alone and under that there is a red paste like a silicon. And I don't know why that jumper was sulfated almost broken or rather red that was the fault I would like to attach an image. I hope it serves as a guide for others who need it thanks friends from venezuela jesus vera

Hi, it seems to have low video output voltage (normally 180v.) Verify the electrolytic. regards

Measure the voltage on DIODE VD 552 which is in the source sslids and comment. There you must have the 180v.

FIND THE TV WITH SHORT TSH, 3 BUTTON PANEL BUTTONS. CONNECT THE UADIO VIDEO CONNECTOR THAT IS IN THE LATERA PART NEAR THE EEPRO AND JUNGLE. WHERE IT DOES NOT GO. WHY CAN IT BE THAT FAIL?
